UNITED ALLEN H. PALMERTON, OF INDIANAPOLIS, INDIANA.

WRECKING FROG.

SFECIPIC'ATION forming part of Letters Patent No. 298,619, dated May 13, 1884:.

Application filed December 21, 1883. (No model.)

To aZZ whom. it may concern..-

Be it known that I, ALLEN H. PALMERTON, a resident of Indianapolis, Indiana, have made certain new and useful Improvements in VVrecking-Frogs, a description of which is set forth in the following specification, reference being made to the accompanying drawings, in the several figures of which like letters indi cate like parts.

My invention relates to devices for replacing derailed cars upon the tracks, and will be understood from the following description.

In the drawings, Figure 1 represents a per spective View of my device with a pair of trucks nearly replaced upon the track. Fig. 2 is an end view of my device with a pair of trucks in a similar position.

In detail, r r are the track-rails; ww, the wheels of a derailed truck; F, a frog-plate, made of iron, one end wider than the other, and increasing in thickness from the wide to the narrow end, so as to form an incline; and f is a projection or flange integral with the plate F, formed or raised the entire length of the plate F and about midway between the sides, and made, preferably. a little wider at the narrow end of the frog-plate F than at the other, making a slight taper, in fact. about one inch in four feet, the object being to strengthen it at the point where the heaviest pressure comes--viz., at the narrow end of the frogplate. This frog-plateFisprovided atitswider end withprongspd'or drivinginto and securing the device to a tie. A clamp, O, underlying both the rail r and plate F, elasps the out-er flange of the rail, as shown in Fig. 1, the inner end of the clamp fitting into a channel in the side of the frog, as shown in Fig. 2, and when the clamp is put in place the frog F is held firmly to the rail atthe upper and to the tie at the lower end. An inclined bar, i, is placed outside the other rail and secured in place by prongs at each end, which are driven into the ties, this being an old and well-known device. This bar is made thick enough at its upper flangef being outside the flange of the inner car-wheel, and as the truck is drawn up this flange gradually crowds the tread of the wheel the derailed car is drawn up the incline, the

over toward the rail, and at the proper 1110- ment, the flange of the other wheel being at that time lifted upon the bar i clear of the adjacent rail, the truck is crowded easily and safely over upon the track by the resistance of the flangcf, and the frog is still in position for any succeeding pair of derailed trucks.

It will be observed that my device operates by the pressure of the flange f against the outside of the flange of the car-wheel, which is substantially flat, while other devices operate against the inner or beveled side of the wheelflange, and under great strain the wheel is pulled or forced over the frog and off the track into the land, and the labor is all lost.

What I claim, and desire to secure by Letters Patent, is the following:

1. The frog-plate F, provided with the central flange, f, in combination with the rail 1' and the clamp O, substantially as described.

2. The frog-plate F, provided with the centr al flange. f, the clamp C, the rails 1", and the inclined bar a, all combined substantially as described.

In witness whereof I have hereto set my hand this 13th day of December, 1883.

ALLEN H. PALMERTON.
